Elementor preview is totally different from live

Salutations,

I’ve been having an incredibly hard time with my website. The Elementor preview is completely different from the live on Desktop, at the very least. I have cleared the cache on all ends, I have flushed whatnot on the Elementor tools section, I have rolled back all the way to Elementor 3.7.0, I have changed the theme from Sydney to WordPress 2016, I have changed from Elementor Canvas to Elementor Full Width, I don’t even have any other plugins enabled. In the “Edit with Elementor” section, everything looks exactly how I want it. It aligns perfectly, it flows smoothly. On the desktop site, things aren’t aligned correctly, some elements are on top of each other. This isn’t even my website, I’ve just been volunteering to assist with it and it’s been driving me absolutely insane. I have tried literally everything, I don’t know what to do anymore.
